The culture of the Mentawai Tribe is closely connected to nature, spirituality, and community life. Traditional customs remain an important part of everyday activities in many villages across the Mentawai Islands.

One of the most important cultural figures is the Sikerei, a traditional healer and spiritual leader. The Sikerei performs rituals, healing ceremonies, and guides the community through spiritual traditions.

Traditional clothing is often made from bark fiber, while natural materials from the forest are used for medicine, tools, and ceremonies. Music, dance, and storytelling are also essential parts of Mentawai cultural life.

Visitors are encouraged to respect local customs, ask permission before taking photographs, and support sustainable tourism that helps preserve indigenous traditions.
